Original application filed September 11. 1905- Serial No. 277.982. Divided and this application filed June 25. 1906.

Serial No. 823.283. i

'Tdiill whom it may concern:

Be it known that I, ENGLAND J. BARKER, a citizen of the United States, and a resident of Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type- Writers, of which the following is a clear, full, and exact description.

My invention. relates to the ribbon feed mechanism of typewriting machines similar to that set forth in a prior application filed by me September 11, 1905,- Serial No. 277,982 (of which this case is a division). In typewriting machines of thisclass the paper is fed to the carriage and platen from one or more rolls of paper supported on a carrier-frame or truck that is mounted at the rear ofthe machine.

The object of my invention is to provide a simple and economically constructed device, by means of which the manifolding ribbon willbe automatically fed step by step through the machine in a positive manner at each longitudinal movement of the carriage. This I accomplish by the mechanism hereinafter fully described and as particularly pointed out in the claims.

In the drawingsz-Figure 1 is a plan view of a typewriter having myinvention applied thereto. Fig. 2 is a side elevation thereof. Fig. 3 is a detail view showing in perspective the adjustable trip for actuating the manifold ink ribbon reels. Fig. 4 is a detail view of the mechanism for intermittently revolving the ribbon spools having the latter in dotted lines.

Referring to the drawings A represents a suitable supporting-frame, and B the transversely reciprocal carriage; Mounted on suitable brackets that are secured to opposite sides of this supporting-frame A are a. pair of spools 2, 2, upon which are wound the usual This ribwhere .it passes through the guide-bracket 4. The

frame-work of the carriage is, preferably, rectangular, and its ends are connected at the rear of the machine by a longitudinal bar a, and near the front of the ma chine is provided with a rearwardly inclined paper guide b, for the revolving platen c, and is arranged in the usual manner at a tangent to the circumferential sides of said platen so as to guide the paper therefrom. A longitudinally disposed cutter-blade C is placed flat against and in front of the lower portion of the shield b, but is separated therefrom a sufficient distance to permit of the work, as it is delivered from the platen c, to pass between it and the shield. This cutter-blade is considerablyv narrower than the shield, and its upper edge is sharpened to facilitate the tearing off of the paper when it is desired to remove the paper from the machine. The ends of this cutterblade project upwards and form arms 0? therefor, the side edge of the upper portions of which latter are provided with downturned lugs n, that are pivotally connected to the ends of the shield adjacent to its upper edge. The arm 0 at one end of the blade 0 is provided with asuitablehandle d, by means of which the blade 0 can be raised or lowered, and, at a. suitable point adjacent to the pivotal lugs 0 its ends are provided with lugs e that are connected by means of contraction springs e to a suitable strap e secured to the upper edge of the ends of the carrier above the portion of flat metal strips D attached direct to the upper edge of the carrier, substantially as shown. The action of the springs e upon the cutter-blade is such as to hold it securely in its position against the shield, or, when raised and moved to the'limit ofits rearward movement, to hold it in the latter position.

The manifolding inking devices of the machine comprise a horizontal ribbon or tape F, extending longitudinally in front of that portion of the platen against which the type of the machine strike. The ends of this ribbon are wound upon reels f, f, mounted and journale'd upon the ends of suitably shaped brackets G, whoseupper elongated endsterminate and are removably secured to the underside of the ends-of the shield b, while the opposite free ends are bent back upon themselves and form a bearing for the lower end of the spindles, upon which the spools are mounted, substantially as shown in Fig.- 4 of the drawings. The spindles h of the reels f, j extend down through said reels and through suitable hearings in the two parallel portions of the downturned crooked outerextremity of brackets G. Between these parallel portions each spindle has a ratchet H secured thereto, and, below said ratchet, a lever I of the first class, loosely fulcrumed thereon, which at, say the right hand end of the machine, has its longer branch cxtending towards the rear, and at the left hand side has'its longer branch extending towards the front of the machine. These levers are kept in a position normally at about right supporting-frame A of the machine) bymeans -of a h, and move thereel f. The arm I can be moved as on a pivot or moved longitudinally, and can be adjusted so as to obtain a longer or shorter sweep of the lover I,

l at a point nearer to. or farther from the end of the reciprocal throw of the carrier. The arm K for engaging at the opposite end of the machine, comprises an L- shapedstrip of metal, one end portion of the horizontal part of which has a longitudinal slot k therein, and is secured to the upper edge of the end of the supporting-frame by means of a thumb-screw N. The opposite end of arm K is uptu'rncd or bent to bring it within the path of the end of the lever I cooperating with the reel f, and said arm can be adjusted in the same manner as arm .7, for thepurpose of regulating and controlling the movement of this latter lever l and of the inking devices. It will be understood that when arm J is in rise, arm K is moved out of the path oi the lever of the, adjacent inking reels, and vice versa. In order to allow levers I to pass their respective sweeps whenthe carriage is reversed, I provide the ends of said levers with trips 0, O, that are pivotally secured thereto. These trips comprise short strips of metal, preferably of the same width as levers I, and

have their unsecured ends projecting beyond the extremity of said lever and, preferably, beveled on one side. Pawls m are maintained in their normal operative position by means of spring p, and when the carriage is approaching the limit of its movement in the proper direction, the vertical edge or deflected portion of the trip will meet the endof .one or the other of the sweep and moves independently on its pivot so as to escape past said arm. When, however, said carriage moves in the opposite direction the trip will engage the arm, and, by means of its engagement with a stop pinq, will not yield independently but will move the lever I with it and thereby cause the pawl to engage the ratchet and revolve the spool a short distance. It is of course desirable to operate the ribbon its full length in one direction and then reverse the same. To do this one of pawls m is disengaged from itsratchet by swinging it away therefrom, in which position its spring p will engage the opposite face of said pawl, while the movement of the carriage is utilized to turn the spool on the opposite end of the machine.

The details of the devices for moving and supporting the rolls of paper at the rear of the machine shown in the drawings form the subject-matter of the prior application above referred to, and it is not necessary herein to describe the same in detail. Suffice it to say, however, that I prefer to employ three rolls of track extends the length of the frame of the machine,

i erases and is rriminted in the endsoi a V-shaped clamp 7, the forward ends of which are booked and adapted to clamp the lower rear rail of the machine by means of bolts or screws 8-. The frame 5 is maintained in an upright position by a yoke 9, the forward corners of which have suitable hooks that engage and are clamped to the rear horizontalbar a of the typewriter carriage.

Upon leaving the rolls, the strips of paper are guided to the platen of the" machine between guide-bars E, E, mounted upon upright brackets on the ends of strips D, attached to the rear of the carriage and there codperate with the ribbons to make manifold copies,

as hereinbefore explained. the opposite lever I of the manifold inking devices What I claim as new is:- 1. In a typewrlting machine a suitable supportingframe, a reciprocal carrier, a platen, and auxiliary inking devices therefor mounted onand movable with said carrler, in combination with stationary means adjustably secured to said frame for actuating said inking devices.

2. In a typewrlting machine, a suitable supportingframe, a reciprocal carrier, a platen, and manifold inking devices therefor mounted on and movable with said carrier, in combination with stationary arms for actuatlng said inking devices secured to said supporting-frame and adjustable pivotally. I
